CONCORD, N.H. — A former Fortune 500 executive charged with second-degree murder in a New Hampshire car crash that killed a Vermont couple has waived a hearing on the evidence against him.

Robert Dellinger, of Sunapee, remains in custody without bond in connection with the Dec. 7 crash on Interstate 89 in Lebanon that killed 29-year-old Jason Timmons and 24-year-old Amanda Murphy, both of Wilder. Murphy was eight months pregnant, and the fetus didn’t survive.

The 53-year-old Dellinger told police he was depressed and trying to kill himself when the pickup he was driving hurtled across the median and went airborne, shearing off the top of the couple’s sport utility vehicle. They were killed instantly.

Attorney R. Peter Decato, who represents Dellinger, said his client agreed to waive his court appearance in Lebanon District Court on Tuesday after prosecutors turned over investigative reports on the crash.

“If we had the probable cause hearing, we would have heard verbally exactly what we’re able to now read,” Decato said in an interview Friday.

The case will be transferred to Grafton County Superior Court for indictment. Decato said he hopes a hearing will be held before the end of January so Dellinger can enter innocent pleas and argue to be released on bond.

Dellinger was initially charged with two counts of reckless manslaughter, but state police upgraded the charges two weeks after the crash to second-degree murder, alleging Dellinger’s conduct showed “extreme indifference to human life.”

Dellinger was senior vice president and chief financial officer at PPG Industries Inc. before he left in 2011 because of health issues. He also held top-level posts at Sprint Corp., Delphi Corp. and General Electric Co.

New Hampshire Senior Assistant Attorney General Susan Morrell said in court last month that Dellinger argued with his wife over his medications on the morning of the crash. He left the house and began to drive around, growing increasingly despondent, she said. A trooper said Dellinger told investigators he intended to kill himself.
